trisha standford earns $300 a week plus a 15% commission only on sales she makes after her first $1,000 in sales if ms standfords sales for one week are $2,500 what is her gross pay for that week

Her gross pay for that week=$525

Step-by-step explanation:

Step 1: Express the gross pay

The gross pay can be expressed as follows;

A=F + (R*T)

where;

A=the gross pay per week

F=fixed income per week

R=commission rate

T=total commission sales

In our case;

F=$300 a week

R=15%=15/100=0.15

T = (2,500-1,000) = $1,500

replacing;

A=300 + (15% of 1,500)

A=300 + (0.15*1,500)

A=300+225=525

A=$525

Her gross pay for that week=$525
